Abstract
The superabsorbent was obtained from acrylic monomers and cross linker. Ultrasound was irradiated from a probe and bath system. The present work investigated the parameters of solvent, ionic strength, pH, acoustic power and pulse. The results show that increasing glycerol in the solution changes the viscosity of the reaction for the better and increases the reaction rate. Another major finding was that increasing ultrasonic power and pulse hastens the reaction. This is due to more cavitations and production of more radicals. These findings provide a better understanding of hydrogel synthesis and enable us to control the pertinent parameters.To study the swelling behavior of obtained hydrogels, the related experiments were performed in different pH. Results showed that ultrasonic acrylic hydrogel are sensitive to pH. Therefore, these hydro gels are capable for fast drug absorption and release according to the high porous structure and swelling control by these parameters.
